Fast food has become so pervasive in the U.S. that popular chains can be found anywhere from truck stops in the middle of nowhere to high traffic shopping centers. So where do Americans love dollar menus, value meals and drive-thru ordering the most? We looked at spending data for the largest 100 cities in the U.S. by population and determined which cities spent the most and ate the most often at the following national fast food chains: McDonald's, Wendy's, KFC, Taco Bell, Subway, Pizza Hut, Arby's, and Burger King.
